LM2593HVT-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2593HVT-ADJ/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-down voltage regulator. It operates with an input voltage range of 4.5 V to 60 V and provides an adjustable output voltage between 1.2 V and 57 V. The device delivers a maximum output current of 2 A at a fixed switching frequency of 150 kHz. Packaged in a TO-220 format with seven pins, it supports surface mount installation and functions within a junction temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix configuration matches the required package type and lead-free status. Confirm that the adjustable output variant aligns with the target voltage design requirements. Ensure compatibility with the intended thermal management strategy given the through-hole mounting style.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust 2 A output capability is needed with a wide input voltage range up to 60 V. The TO-220 package facilitates easier heat dissipation compared to smaller surface-mount options. Consider the fixed 150 kHz frequency when designing the external inductor and capacitor values for optimal ripple performance.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2593HV series, which offers higher voltage tolerance than standard LM2593 devices. It shares architectural similarities with other SIMPLE SWITCHER regulators but distinguishes itself through its specific current rating and through-hole packaging option suitable for high-power applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2593HVT-ADJ/NOPB serves as a direct replacement for older LM2593HVT-ADJ variants. Verify pinout compatibility when substituting with non-NOPB versions to ensure proper lead-free compliance and environmental standards are met.
